Corsa Coolant Loss

My 2009 Vauxhall Corsa (gasoline engine) is acting up. Coolant level is constantly low, check engine light is on, and there's an error stored in the memory. Suspect low coolant, any ideas?

I had a similar issue with my Corsa. Coolant disappearing act, check engine light, the whole shebang. First, check your radiator cap – sometimes it's just a faulty seal. Then, give the coolant reservoir a good once-over for any cracks or leaks. Had the cooling fan ever been replaced? What about the radiator hoses? Are they in good condition?

Radiator cap seems fine, and I can't see any obvious leaks around the reservoir. You mentioned the fan, why is that relevant?

The fan's relevant because overheating from low coolant can fry it. I also forgot to mention something very important: The water pump can also be a cause, if the check engine light stays on, you better take it to the workshop right away. They found a hairline crack in mine that was causing a slow leak. I spent 52€ to repair this issue. Best to get it pressure tested professionally rather than chasing ghosts.

Thanks for the insight. I'll get it checked out by a mechanic ASAP. Seems beyond my limited skills.
